Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595882, here are decompositions:

13 + 31595869 = 31595882
151 + 31595731 = 31595882
163 + 31595719 = 31595882
181 + 31595701 = 31595882
211 + 31595671 = 31595882
229 + 31595653 = 31595882
271 + 31595611 = 31595882
313 + 31595569 = 31595882

Showing the first eight; more decompositions exist.
